Here are some top banks in Nigeria that are crypto-friendly and may facilitate Bitcoin transactions:
Even if the bank claims to openly be friendly with cryptocurrency, you have to be wise and careful in this our country, where you know that the government is against cryptocurrency and can suddenly launch a manhunt for people involved in cryptocurrency, and the banks will be the first institutions that they will tax with providing names of people who have made transactions regarding cryptocurrency. One particular reason why you should be careful about trusting any bank is because even though they claim now to support cryptocurrency, they are still under the institution of the government and will act in accordance with whatever the government demands.
Banks and government na the same people, entity, body or whatever, these set of people never love what breaks their ego and these people love it when citizens dance to their tone than even money. Banks and government are very sensitive and intelligent to entangling people to work for them and receive peanuts from them, so if they are claiming to be involving themselves in crypto then that's a bait to hunt out their victims. If you are caught using crypto in a business transaction then you'll see whether them be your friends or not, you'll pay for it.
It's always advisable to keep clear from bank and government when relating to cryptocurrency untill further public announcement is made to now accepting crypto in any their services. Infact, if such news is made then they going to come with a huge regulations that would favour them more than the users.
